摘要： Apparatus for analyzing particles contained in a fluent medium (12). The apparatus includes a body (20) having a window (30), an optical source preferably comprising a laser diode (100) having a small light emitting area (140), and an optical system (102) for focusing the light from the laser diode at a focal spot (84) such that the size of the focal spot is approximately equal to the size of the light emitting area of the laser diode. A photodetector (106) is mounted in the body and detects light backscattered from the focal spot by particles in the fluent medium, and produces an electrical signal that comprises a series of pulses associated with the particles. The electrical signal is input to a detector that counts the pulses and indicates the number of particles in the fluent medium. The detector includes discrimination means for preventing the counting of a pulse that has a rise or fall time above a predetermined threshold, thereby discriminating against particles that are not at the focal spot. Means are provided for measuring the integrated amplitude of the electrical signal, and for varying the distance between the focal spot and the window to maximize such integrated amplitude. An intrinsically safe embodiment is also disclosed in which the probe positioned at the measuring site does not include any electrical components. This embodiment may be implemented using light of multiple wavelengths for characterizing individual particles.

摘要： A relative reflective photometry instrument is provided for measuring surface reflectance of a specimen (17) and comprises a light source (1) at one end and a pair of photosensors (9, 23) at the other end, one of the photosensors (9) being positioned to receive rays directly from the light source and the other (23) being positioned to receive light scattered from the specimen. The photosensors are provided with a central opening (13) through which a portion of the light passes onto the specimen (17) and is thereafter reflected onto the photosensor (23). A comparing circuit (5, 79) can comprise a divider for establishing the ratio between the signals extracted from the two photosensors.

摘要： Un procédé permet de mesurer l'angle des fibres dans un matériau fibreux solide (12) par rapport à trois axes de référence orthogonaux entre eux. Il convient particulièrement pour mesurer le grain incliné et l'angle de la surface du grain dans du bois. Le procédé se fonde sur la mesure de l'intensité de la lumière réfléchie à différents angles azimutaux lorsqu'un faisceau de lumière (14) de petit diamètre est projeté sur la surface (12). La nature des réflexions spéculaires (20) d'un faisceau de lumière (14) frappant la surface d'un cylindre (12) sert de modèle pour le système. Un appareil préféré d'application du procédé comprend une source de lumière, qui peut être un laser de faible puissance, dirigée perpendiculairement sur la surface du matériau fibreux (12). Une pluralité de photosenseurs (22, 24, 26, 28) situés sur un plan (30) perpendiculaire à l'axe du faisceau de lumière (14) sont placés autour de la source de lumière pour détecter la lumière réfléchie selon différents angles azimutaux. Lorsque les fibres du matériau (12) sont perpendiculaires au faisceau de lumière (14), la lumière réfléchie maximale est perçue à des positions écartées de 180o l'une de l'autre et perpendiculaires à l'axe longitudinal des fibres. Si l'axe de fibres dans le matériau (12) est incliné et non plus perpendiculaire par au faisceau incident de lumière (14), même que la surface du matéraiu (12) soit perpendiculaire, l'angle azimutal entre les positions de la lumière réfléchie maximale diminue en fonction de l'angle d'inclinasison des fibres. D'autres procédés comprennent l'utilisation d'un photosenseur sur un axe (52) avec une série multiplexée de sources de lumières (58) agencées autour de l'axe (52). Ces lumières (58) peuvent être utilisées simultanément, si elles ont des longueurs d'onde diverses, et les photosenseurs (92, 94, 96, 98) emploient un système de division (86) et de filtrage du faisceau sensible à chaque différente source de lumière (72, 74, 76, 78).

摘要： The present invention provides an apparatus and method to determine individual red blood cell shape within a flow cytometric aperture. Cell shape is determined by measuring the asymmetry of a light scatter pattern produced by laser illumination of the cell within the aperture by light scatter detectors which collect light from specific angular regions of light scatter, and analyzing the asymmetry of the light scatter patterns to determine the individual red blood cell shape. Embodiments of the invention further provide for the determination of red blood cell shape by measuring the asymmetry of a light scatter pattern and measuring electrical resistance of the red blood cell.
